The RefSeq mRNAs gene track for the 23 Dec 2019 Aythya fuligula/GCA_009819845.1_bAytFul2.alt genome assembly displays translated blat alignments of vertebrate and invertebrate mRNA in GenBank.
Total genome size: 1,013,629,683
Gene count: 12,117
Bases in genes: 377,148,423
Percent genome coverage: % 37.208
The mRNAs were aligned against the Aythya fuligula/GCA_009819845.1_bAytFul2.alt genome using translated blat. When a single mRNA aligned in multiple places, the alignment having the highest base identity was found. Only those alignments having a base identity level within 1% of the best and at least 25% base identity with the genomic sequence were kept.
Specifically, the translated blat command is:
blat -noHead -q=rnax -t=dnax -mask=lower target.fa query.fa target.query.psl where target.fa is one of the chromosome sequence of the genome assembly, and the query.fa is the mRNAs from RefSeqThe resulting PSL outputs are filtered:
pslCDnaFilter -minId=0.35 -minCover=0.25 -globalNearBest=0.0100 -minQSize=20
-ignoreIntrons -repsAsMatch -ignoreNs -bestOverlap
all.results.psl GCA_009819845.1_bAytFul2.alt.xenoRefGene.psl
The filtered GCA_009819845.1_bAytFul2.alt.xenoRefGene.psl is converted to
genePred data to display for this track.
The mRNA track was produced at UCSC from mRNA sequence data submitted to the international public sequence databases by scientists worldwide.
